Specification of Letters Patent No. 10,905, dated May 16, 1854.

To aZZ whom t may concern Be it known that I, HIRAM FRIsEE, of Olmstead,inthe county of` Cuyahoga and State of Ohio, have invented new anduseful j Improvements in the Construction of Lath- Machines; and I dohereby declare that. the following is a full and exact descriptionthereof, reference being had to the annexed drawings, making part ofthis specification.` The nature of my invention consists 1n hanging thelog upon centers ina carriage l the log, as it traverses over the saws;also in the combination of devices for adjusting the log to the saws, sothat lath, or strips of any desired thickness or width may be cut fronrthe log; and also, in revolving the log by the action of a ratchet, thethickness of a lath,? immediately on each strip or lath being cnt fromthe log. i j

To enable `others skilled in the art, to,y make and use my invention, Iwill proceed to describe its construction and operation. j

Figure l, is a plan Xiew of the machine; Fig. 2, a side elevation, Fig.3, a transverse section Aof the frame, without the carriage, inthefdirect-ion of the red lines X X, of Fig.

riage without the frame, in the direction of the lines X X Fig. 1. Theother view willV be referred to in description.

Like let-ters refer to like parts in the dif ferent views.

A, represents the log, hung in the carriage B B, by the centers C C,upon which it revolves, and which centers are se'cured to the slides CC, Figs. 1, ande; these centers re tain the log in place, but do notsustain the whole weight of;it, as the log rests on the j rollers D D.The rollers revolve upon the each time it passes its lengt-h over thesaws F F, in either direction longitudinally, by the ratchet G, Figs. 1and 4, which is con-` nected at the lower end, to the stay lever H,

by a joint. The stay lever is hung upon l journals near its center, tothe under sideof the carriage.

As the carriage passes over either of the cam blocks, 'I I, in thedirection of the arrows, it brings the stay lever `in Contact with themalternately, and by the `inclined planes of the cam blocks, over whichslides the stay lever, the end to which the weight J is hung, is raised,and the other end, to which the ratchetI is attached, `is depressed;thereby revolving the log, as t-he ratchet teeth are forced into it bythe spring G, and its own inclination. As soon as the stay lever passesthe cam blocks, by the action of the weight, a reverse movement is givento the stay lever, which relieves the ratchet teeth from the log, andcauses the point H of the lever, as seen in Fig.A 4, to be forced intoit; which secures the log in place while traversing over the saws.

The movements for rotating the log, take place directly after it leavesthesaws. It matters not in which direction the ylog may be traversing,the result is the saine, butas the carriage returns in a reversedirection of the arrows, the stay lever againpassesWover` i the camblocks, but as they are hung upon a center pin, they turn upon it by thelever,

until the stay lever passes over it, then turns back to its place, andis prevented from `turningonly in the desired direct-ion, by the staypins I I", which are inserted inthe side of the frame.` The logisprevented from turning' more than the thickness of a lath, by the rollerD3, Figs. 3, 4, and 5, against Y which the shoulder or scaf, in thelogrests,`

as it traverses. These rollers are supported i by the arms D4 which aresecured to the frame, d, are keys tor adjusting the arms to the log. Thetraversing .movement is lgiven to the carriage B B, by the rack andpinion K and K, the pinion 1being keyed to thesame shaft as thatonwhichthe clutch loose pulleys L, and L', are keyed. These clutch loosepulleys belt out to the, tight pulleys M M. l l i On the other end ofthe" same shaft `to `.which the tight pulleys are attached, is thedriving pulley N, on` the outside of the frame. `By t-his `arrangementof belt-s and pulleys, any movement given -to the driving pulley N,causes a corresponding movement to be conveyed to thefpinion K, whichtraversesthe carriage, by means of the `rack K.

The forward` and backward traverse of ioc ' cuts the lath 0Ehorizontally, and the saw.

from the clutch P, to the clutch P', which,

,the pulleys clutch and unclutch, by the Y over the saws, a lath is cutoff.

yfast as cut from the log.

vwhich the carriage traverses on the ways Vshaft W, which is driven bybelting from .by which a motion is conveyed to the pulley the carriageis obtained by cross belting, as j follows: The driving wheel N, turningin the direction of the arrow, causes the carriage to move from theposition it now has in Figs. l and 2, and by the action of the pin O,the shifter O is moved, thereby the pulleys L and L are shifted on theshaft, from the pin P, to P, which causes the carriage to move to I,then by the action of the pin O, 'on the shifter, the direction of thecarriage will be again reversed by the cross belt, on connecting thepulley L, to M, by which it will traverse to I, then again the reactiontakes place as before described. This reverse traversing of the carriagefrom I, to I, and from I to I, is produced by the belts on the pulleys Land L, and M and M Fig. 1 the belt o-n the pulley L and M, being a crossbelt, and the other straight.

In combination with the clutch and pins P and P, the pulley is moved bythe shifter by the cross belt moves the carriage to I, leaving thepulley L to run loose; when the pulleys are again shifted from P to P,the pulley L clutches, as seen in Fig. l, leaving the .pulley L to runloose, thus alternately action of the shifter, which gives the reversetraverse of the carriage, on the frame over the saws. Each time the logtraverses The lath being cut oft from the log, drop upon onelof theaprons or conveyers, Q Q, according tothe position of the log over eachapron or conveyer. These conveyers revolve upon the rollers R R, whichare turned by the belt S, from the pulley S', Figs. 2 and 3. By thisarrangement the lath are conveyed to the front of the machine, forbundling, as

e On the front of the machine is the indeX plate T, for counting thelath; this machine is-operated by the pall and ratchet T and T, Fig. 1.The ratchet is on the opposite end of the shaft, to which the pointeris, and is worked by the pall T, attached to the carriage.

' Cn the under side of the carriage are wheels, as seen at U U, Figs. 2and 4f, upon U U', which ways are secured to the frame VV. Inside of theframe are the circular saws F and F. The saw F, is secured to the sameshaft as the driving pulley N, as seena't W, Fig. 3, and the saw F is onthe the shaft W, to the shaft X, by the belt-X',

V, by the crossbelt X, which is on the same shaft as the saw F, whichshaft has a point and step at-the bottom. The saw F `of sawing.

The arms DL D4, slide inthe frame, and are secured in place by the keysd d. These sliding or adjustable arms, in combination with the rollers DD, upon which the log rests, and the slides D D, provided withV theadjusting screws E E, are the means employed for the Vpurpose ofadjusting the log to the saws, so that lath or strips, of any thicknesso-r width, may be cut from the log.

The adjusting screws will raise or lower the log in a vertical directionfrom or to, the log, according to the required width of the lath orstrip; and the'arms D4 D4, adjust. the log horizontally to the saws,according to the required thickness of the strips or lath.

Lath which are sawed from the log, are superior in all cases, to lathcut from the log, by means of knives, in the latter case,

the lath are invariably checked or split by the action of the knives, insevering them from the log, and when the log is knotty,

portion of the lath are worthless by their` being so split and brokenup, by the wrenching of the knives and log.

When saws are used the lath are of uniform thickness and width, free'from checks,

as the saws will cut through the log withy out its starting or divergingfrom the saws, or the saws from the log, which is found not to be thecase when knives are used.

Vihat I claim as my improvement, and desire to secure by Letters Patent,is-

1. The combination of the movable cam blocks I I, stay lever H, ratchetdog G, and weight J, for the purpose of successively turning andgripping the log, in the following-'manner, the ratchet dog rotates thelog the thickness of a lath as the stay leverl passes over the movablecam blocks I I on the instant the stay lever passes the movable camblock, the stay lever is reversed by the action of the weight J causingthe log to be gripped and held stationary by the point of the lever atI-I during the process The act of turning and gripping the log takesplace alternately as the carriage traverses backward and forward in thedirection of the arrows.

2. I claim the combination of the adjustable rollers D, D, and D3, D3the slides D D and the adjusting screwsv E E with the slides C C ashereinbefore described, and for the purpose set forth.
